[1] The bottles are clustered around a cylinder situated in the center of the assembly, [1] where there is a sensing system called Sea-Bird or CTD, that stands for "Conductivity, Temperature and Depth", although other variables ...
This arrangement conveniently allows for a large number of Niskin bottles to be mounted together in a circular frame termed a rosette. [2] As many as 36 bottles may be mounted on a single rosette.

The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette. The sampling bottles close at predefined depths, triggered either manually or by a computer, and the water samples may subsequently be analyzed further for biological and chemical parameters. The CTD may also be used for the calibration of sensors.
